Burst Mode in Lumia Camera 5 on the 830

Hello. I have a Lumia 830 with Denim and Lumia Camera 5. ​ ​Is there a good way to capture bursts apart from Rich Moments? I am avoiding Rich Moments because the 830 can only do 2K capture and the resulting stills are low res.

The old Lumia camera had a smart sequence mode which made it easy to extract full-res stills from bursts. The new version 5 does support bursts by doing a long press of the camera button, but it is quite slow and it populates the photo app with multiple photos with no easy way to select the best shot.
